This is a 16 bit cpu. Job was installed by a 3rd party not thyssen. cpua program is for 32 bit jobs but I did try it. No luck. Just to make sure the laptop was working I deleted another job and then created it again from scratch and it worked. This is the first job Ive had trouble connecting to. I am curious about the jumper config on the 6300vf2 and the 6300vh3. don't know if they might have something to do with problem. Making things worse is the fact the UIT has been removed.
